In this work, an advanced algorithm for the mechanical calculation of the catenary
system in a railway is presented. The main objective is to allow an increment in the
speed in railways, by developing an accurate mechanical calculation of the catenary.
Among the different types of these kind of electrical systems, the so called
stitched catenary presents a better dynamical behaviour, because it maintains a
more uniform stiffness along the span. Of course, the price to be paid consists of
a greater complexity due to the existence of two kinds of carriers, the main and
the secondary ones. Finally, the presented algorithm will be used to implement a
software tool.
Keywords: mechanical forces, stitched catenary, droppers length.
